• Fused Silica

Product Description And Parameters

Main Composition:SiO2

Raw Material:Quartz sand

Capacity:1000 tons per month

Color:White

Size:As your requirements

Fused Silica is made of high purity quartz sand by electrically fused in electric arc furnaces, then the crystalline quartz sand transformed into amorphous silicon dioxide.

Features
1.Low thermal conductivity.
2.Low thermal expansion.
3.Small heat capacity.

Application
Mainly used for manufacturing glass, refractory materials, smelting ferrosilicon, coatings, rubber fillers, metallurgical flux, ceramics, abrasive materials, and also for metal surface treatment. In construction, it can be used to make acid-resistant concrete and acid-resistant mortar because of its strong resistance to acid media.
